Try this: (I just tested it on a vista machine)
1 - load card into computer
2 - click start menu (the circular icon with the windows flag) located at the bottom left of your screen
3 - You'll see 2 columns of choices and in the right column you'll see a choice that says computer - click it
4 - At this point you should see the card and all the other drives that are attached to the computer.
So just click the card, then click down into the folder that has the pics.
Hope that may help
